Same error if I add the following line to /etc/fstab: devpts /dev/pts devpts gid=5,mode=620 0 0
I experience the same problem. A few checks give me: # mount | grep pts devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) but: # grep pts /proc/mounts devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600,ptmxmode=000 0 0 The problem is somehow related to eblit-glibc-pkg_preinst() in /usr/portage/sys-libs/glibc/files/eblits/pkg_preinst.eblit. But I don know whats wrong.

Should the suid flag be added to /etc/portage/package.use? I am not too clear on what this new suid flag does for glibc2.16?
Please attach the entire build log to this bug report.
I think the error is in the pkg_preinst.eblit file Line 57 reads: if awk '$3 == "devpts" && $4 ~ /[, ]gid=5[, ]/ { exit 1 }' /proc/mounts ; then but it should be: if awk '$3 == "devpts" && $4 !~ /[, ]gid=5[, ]/ { exit 1 }' /proc/mounts ; then That is the error i triggered if "gid=5" is NOT present (i.e. !~) in /proc/mounts

bzip2 compressed build log (less than 200KB) does not upload when I press submit from bugs.gentoo.org??
I just realised the following behavior of /proc/mounts: after a fresh reboot it includes the line: "devpts /dev/pts devpts rw,relatime,gid=5,mode=620 0 0" but after the first sudo su command the devpts line becomes: "devpts /dev/pts devpts rw,relatime,mode=600 0 0" the "gid=5" is gone! may be this is part of the issue

(In reply to fcrvincent from comment #12) i doubt sudo or su is messing with your mounts. are you sure you don't have commands in your root's login shells that are doing this ? glibc is correct -- if your /dev/pts is mounted this way, it is broken, and it should not let itself be installed.
My bad it was a bashrc in my root directory that messed up my devpts mount! Many thanks for your great support and sorry for the false alarm..
